In this way, indirect communication between the user equipment and the wearable device is implemented by using the network connection device, so that the user equipment and the wearable device are not limited by a communication range.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.15/511,123, filed on Mar. 14, 2017, which is a national stage ofInternational Application No. PCT/CN2014/086492, filed on Sep. 15, 2014.All of the aforementioned patent applications are hereby incorporated byreference in their entireties.

TECHNICAL FIELD

The present disclosure relates to the field of communicationstechnologies, and in particular, to a communications method of awearable device, a communications system, and a related device.

BACKGROUND

A wearable device such as a smart watch or a band usually communicateswith a terminal device such as a mobile phone in a BLUETOOTHcommunication manner to implement functions such as event notificationor information synchronization. For example, when the mobile phone hasan incoming call, the smart watch may be notified in the BLUETOOTHcommunication manner, and then the smart watch has incoming callnotification. The wearable device brings convenience to a user, andtherefore is drawing attention from more equipment vendors.

At home, the wearable device and the terminal device may be placed atdifferent locations. For example, the mobile phone is in a bedroom whilethe band is worn by a user in a living room, in this case, the mobilephone is far away from the band, because a communication coverage areaof the BLUETOOTH is relatively small, the mobile phone cannotcommunicate with the band by using the BLUETOOTH such that communicationbetween the mobile phone and the wearable device cannot be maintained.

Thedescribed embodiments are merely some but not all of the embodiments ofthe present disclosure. All other embodiments obtained by a person ofordinary skill in the art based on the embodiments of the presentdisclosure without creative efforts shall fall within the protectionscope of the present disclosure.

In the specification, claims, and accompanying drawings of the presentdisclosure, the terms “first”, “second”, “third”, “fourth”, and so on(if existent) are intended to distinguish between similar objects but donot necessarily indicate a specific order or sequence. It should beunderstood that the data termed in such a way are interchangeable inproper circumstances so that the embodiments of the present disclosuredescribed herein can be implemented in orders except the orderillustrated or described herein. In addition, the terms “include”,“contain” and any other variants mean to cover the non-exclusiveinclusion, for example, a process, method, system, product, or devicethat includes a list of steps or units is not necessarily limited tothose units, but may include other units not expressly listed orinherent to such a process, method, system, product, or device.

An embodiment of the present disclosure provides a communications methodof a wearable device that may be mainly applied to data communicationssystems shown in FIG. 1A and FIG. 1B. The communications system shown inFIG. 1A includes user equipment, a wearable device, and a networkconnection device. The user equipment may be a device that can access anetwork by using a network connection device, such as a mobile phone, aPad, or a personal computer. The wearable device may be a device thatcan be used by pairing with the user equipment (for example, the smartband in FIGS. 1A-1B), such as a smart band or a smart watch. The networkconnection device may be a device that has a network connectionfunction, such as a home Wi-Fi router and a gateway. In an embodiment ofthe present disclosure, the network connection device may require aBLUETOOTH function.

Generally, a communication connection between the user equipment and thewearable device may be directly established, for example, a BLUETOOTHcommunication connection. The user equipment may send a message to thewearable device for execution. For example, when the user equipment hasan incoming call, the user equipment may send a message to the wearabledevice, and the wearable device displays the incoming call of the userequipment.

In this embodiment, however, when the communication connection betweenthe user equipment and the wearable device is disconnected because ofreasons such as a distance, an indirect communication connection betweenthe user equipment and the wearable device may be implemented by usingthe network connection device. A communication connection that is of aprotocol and that is between the network connection device and the userequipment is established, for example, a communication connection of theUPnP protocol or a communication connection of the Wi-Fi protocol. Acommunication connection that is of a BLUETOOTH protocol is establishedbetween the network connection device and the wearable device. A messagesent by the user equipment to the wearable device may be indirectlytransmitted to the wearable device by using the network connectiondevice.

The communications system shown in FIG. 1B includes the user equipment,the network connection device, the wearable device, and at least onebridge device. For a connection between the user equipment and thenetwork connection device, refer to the connection between the userequipment and the network connection device in FIG. 1A. Each bridgedevice may be connected to the network connection device by using anelectrical power cable, the communication connection that is of theBLUETOOTH protocol may be established between the network connectiondevice and the wearable device by using any one of the bridge devicessuch that the network connection device may encapsulate the informationsent by the user equipment into a BLUETOOTH packet, and transmit theBLUETOOTH packet to the bridge device by using an electrical power cableprotocol, and then the bridge device transmits the BLUETOOTH packet tothe wearable device.

Main functions of the bridge device are to ensure a coverage area ofcommunication between the network connection device and the wearabledevice and to ensure that a message sent by the network connectiondevice may arrive to the wearable device.

The communications method of a wearable device in this embodiment of thepresent disclosure is performed by the network connection device in thesystem shown in FIG. 1A or FIG. 1B. A flowchart is shown in FIG. 2,including the following steps.

Step 101: Determine that a second BLUETOOTH connection between the userequipment and the wearable device is disconnected, and establish a firstBLUETOOTH connection between the network connection device in a networkto which the user equipment belongs and the wearable device.

Generally, the second BLUETOOTH connection between the user equipmentand the wearable device is established, and the user equipment maydirectly communicate with the wearable device. If the second BLUETOOTHconnection is disconnected, in this embodiment, to implement that theuser equipment indirectly communicates with the wearable device by usingthe network connection device, the network connection device separatelyestablish a communication connection to the wearable device and acommunication connection to the user equipment. For a communicationconnection between the network connection device and the user equipment,if the user equipment accesses the network by using the networkconnection device, the communication connection between the networkconnection device and the user equipment is established. For acommunication connection between the network connection device and thewearable device, establishing the first BLUETOOTH connection between thenetwork connection device and the wearable device may be triggered inthe following cases:

(1) When the user equipment finds that the second BLUETOOTH connectionto the wearable device is disconnected, or when the user equipment findsthat a third communication connection to the network connection deviceis established, the user equipment may directly send a triggeringcommand to the user network connection device, where the triggeringcommand is used to instruct to establish the first BLUETOOTH connectionbetween the network connection device and the wearable device. Whenreceiving the triggering command sent by the user equipment, the networkconnection device may determine that the second BLUETOOTH connectionbetween the user equipment and the wearable device is disconnected, andactively establish the first BLUETOOTH connection to the wearabledevice. After receiving the triggering command, the network connectiondevice sends a BLUETOOTH paging message. When finding that the secondBLUETOOTH connection to the user equipment is disconnected, the wearabledevice determines whether the BLUETOOTH paging message sent by thenetwork connection device can be received. In an embodiment, if thesecond BLUETOOTH connection between the wearable device and the userequipment is not disconnected, the wearable device still detects in realtime whether the BLUETOOTH paging message sent by the network connectiondevice is received, if the BLUETOOTH paging message is received, aBLUETOOTH paging response is sent to the network connection device, ifthe network connection device receives the BLUETOOTH paging responsesent by the wearable device, the first BLUETOOTH connection to thewearable device is established.

(2) After finding a BLUETOOTH signal of the wearable device, the networkconnection device determines that the second BLUETOOTH connectionbetween the user equipment and the wearable device is disconnected. Thenetwork connection device may periodically send the BLUETOOTH pagingmessage. When finding that the second BLUETOOTH connection to the userequipment is disconnected, the wearable device determines whether theBLUETOOTH paging message sent by the network connection device can bereceived. In an embodiment, if the second BLUETOOTH connection betweenthe wearable device and the user equipment is not disconnected, thewearable device still detects in real time whether the BLUETOOTH pagingmessage is received, if the BLUETOOTH paging message is received, theBLUETOOTH paging response is sent to the network connection device, ifthe network connection device receives the BLUETOOTH paging responsesent by the wearable device, the first BLUETOOTH connection to thewearable device is established.

(3) After finding a BLUETOOTH signal of the wearable device, the networkconnection device sends an acknowledgment request message to the userequipment, where the acknowledgment request message is used to requestthe user equipment to determine whether the first BLUETOOTH connectionbe established between the network connection device and the wearabledevice. If an acknowledgment message returned by the user equipment isreceived, the network connection device determines that the secondBLUETOOTH connection between the user equipment and the wearable deviceis disconnected, and then establishes the first BLUETOOTH connection tothe wearable device, if an unacknowledgment message returned by the userequipment is received, the first BLUETOOTH connection may be notestablished.

It should be noted that, in the second case, after the networkconnection device finds the BLUETOOTH signal of the wearable device anddetermine the second BLUETOOTH connection, the first BLUETOOTHconnection is established, or after the network connection device findsthe BLUETOOTH signal of the wearable device, the first BLUETOOTHconnection is first established, and then the user equipment disconnectsthe second BLUETOOTH connection to determine that the second BLUETOOTHconnection is disconnected.

It should be noted that, in the two cases of the communications systemsshown in FIG. 1A and FIG. 1B, the established first BLUETOOTHconnections between the network connection device and the wearabledevice are different. In the system shown in FIG. 1A, a direct firstBLUETOOTH connection between the network connection device and thewearable device is established, however, in the system shown in FIG. 1B,an indirect first BLUETOOTH connection between the network connectiondevice and the wearable device is established by using a bridge devicethat communicates with the network connection device.

It should be further noted that, optionally, after the first BLUETOOTHconnection between the network connection device and the wearable deviceis established, the network connection device may further send anannouncement message to the user equipment, where the announcementmessage is used to notify the user equipment that the first BLUETOOTHconnection between the network connection device and the wearable deviceis established such that the user equipment may send first informationto the wearable device by using the network connection device.

Step 102: The network connection device receives first information thatis sent by the user equipment through a third communication connectionto the network connection device, where the first information is sent tothe network connection device by the user equipment through the thirdcommunication connection when the second BLUETOOTH connection betweenthe user equipment and the wearable device is disconnected.

Step 103: The network connection device sends the first information tothe wearable device through the first BLUETOOTH connection establishedin step 101.

After the first BLUETOOTH connection between the network connectiondevice and the wearable device is established, the user equipment mayfirst send, to the network connection device, the first information tobe sent to the wearable device, and then the network connection devicesends the first information to the wearable device. The firstinformation may be content, an instruction, data, and the like that issent by the user equipment to the wearable device. A format of the firstinformation sent by the user equipment to the network connection devicemay be the same as or different from a format of the first informationsent by the network connection device to the wearable device. When theuser equipment sends the first information to the network connectiondevice, a communications protocol format supported by the thirdcommunication connection may be used, and when the network connectiondevice sends the first information to the wearable device, a BLUETOOTHprotocol format is mainly used. Therefore, in a specific operation, thenetwork connection device may convert first information in thecommunications protocol format supported by the third communicationconnection to first information in the BLUETOOTH protocol format.

In an embodiment, the third communication connection between the networkconnection device and the user equipment may be a communicationconnection that supports the IP such that the network connection devicemay receive the first information sent by the user equipment by usingthe IP. In an embodiment, the network connection device may receive thefirst information that is in the BLUETOOTH protocol format and that iscarried in a payload of an IP packet, and send the first information tothe wearable device through the first BLUETOOTH connection, or thenetwork connection device may receive first information that is in anupper-layer protocol format and that is carried in an IP packet, andsend the first information to the wearable device through the firstBLUETOOTH connection. Upper-layer protocols include but are not limitedto the UPnP protocol, the Digital Living Network Alliance (DLNA)protocol, the Intelligent Grouping and Resource Sharing protocol (IGRS),which is also referred to as the IGRS protocol, the Hypertext TransferProtocol (HTTP), the Transmission Control Protocol (TCP), and the UserDatagram Protocol (UDP). The network connection device converts thefirst information in the upper-layer protocol format to the firstinformation in the BLUETOOTH protocol format.

The third communication connection may further be a communicationconnection that supports the UPnP protocol. The network connectiondevice may receive first information that is in the UPnP protocol formatand that is sent by the user equipment, or convert first information inthe UPnP protocol format to first information in the BLUETOOTH protocolformat, and then send the first information to the wearable devicethrough the first BLUETOOTH connection.

The third communication connection may further be a connection thatsupports the Wi-Fi protocol. The network connection device may receivethe first information that is in the BLUETOOTH protocol format and thatis in a payload of a Media Access Control address (MAC) frame of theWi-Fi protocol, and send the first information to the wearable devicethrough the first BLUETOOTH connection, or the network connection devicemay receive the first information that is in an upper-layer protocolformat and that is sent by the user equipment by using the Wi-Fi, andconvert first information in the upper-layer protocol format to firstinformation in the BLUETOOTH protocol format, and send the firstinformation to the wearable device through the first BLUETOOTHconnection. Upper-layer protocols include but are not limited to theUPnP protocol, the DLNA protocol, the IGRS, the HTTP, the TCP, the UDP,and the IP.

It should be further noted that, when the network connection devicesends the first information through the first BLUETOOTH connection, forthe system shown in FIG. 1A, the network connection device may directlysend the first information to the wearable device, for the system shownin FIG. 1B, the communication connection of the BLUETOOTH protocol maybe established between the network connection device and the wearabledevice by using any one of the bridge devices such that the networkconnection device may encapsulate the first information sent by the userequipment into the BLUETOOTH packet, and transmit the BLUETOOTH packetto the bridge device by using the electrical power cable protocol, andthen the bridge device sends the BLUETOOTH packet to the wearable devicein a communication range of the bridge device.

Further, for second information actively sent by the wearable device tothe user equipment, the network connection device receives the secondinformation that is sent by the wearable device through the firstBLUETOOTH connection, where the second information may be a notificationor data that is sent by the wearable device to the user equipment,information that is reported by the wearable device to the userequipment, or the like. The network connection device may send thesecond information to the user equipment through the third communicationconnection to the user equipment. A format of the second informationsent by the wearable device to the network connection device may be thesame as or different from a format of the second information sent by thenetwork connection device to the user equipment.

It can be learned that in the method of this embodiment, if a secondBLUETOOTH connection between user equipment and a wearable device isdisconnected, a first BLUETOOTH connection is established between anetwork connection device and the wearable device, and the networkconnection device may send, to the wearable device through the firstBLUETOOTH connection, first information sent by the user equipment. Inthis way, indirect communication between the user equipment and thewearable device is implemented by using the network connection devicesuch that the user equipment and the wearable device are not limited bya communication range.

It should be noted that, in the communications method in steps 101 to103, the user equipment indirectly communicates with the wearable deviceby using the network connection device in the network to which the userequipment belongs. In one case, under any one of following conditions,the first BLUETOOTH connection between the network connection device andthe wearable device is disconnected, and the user equipment directlycommunicates with the wearable device

The network connection device receives a first notification message sentby the user equipment, where the first notification message is used toinstruct the network connection device to disconnect the first BLUETOOTHconnection between the network connection device the wearable device,and the third communication connection between the network connectiondevice and the user equipment is disconnected.

It should be further noted that, the communications method in steps 101to 103 indicates communication that is performed after each device inthe system shown in FIG. 1A or FIG. 1B is configured. Therefore, beforestep 101, the user equipment further configure the network connectiondevice. In an embodiment, before step 101, the network connection devicemay further perform a configuration step in any one of the followingmanners. A flowchart is shown in FIG. 3, including the following steps.

(1) The user equipment directly performs configuration.

Step 104: The network connection device receives a first configurationinformation sent by the user equipment, where the first configurationinformation includes a BLUETOOTH address of the wearable device and akey for communication between the network connection device and thewearable device, and may further include information such as a pairingrelationship between the user equipment and the wearable device. Thenetwork connection device stores the first configuration information,where the first configuration information is used by the networkconnection device to send the first information to the wearable devicethrough the first BLUETOOTH connection. Optionally, if the firstconfiguration information includes no pairing relationship between theuser equipment and the wearable device, the network connection devicemay generate the pairing relationship between the user equipment and thewearable device according to the first configuration information.Therefore, when information is transmitted between the networkconnection device and the wearable device, the network connection devicemay establish the first BLUETOOTH connection according to the firstconfiguration information and transmit the information through the firstBLUETOOTH connection.

Further, the network connection device may further receive secondconfiguration information sent by the user equipment, and the secondconfiguration information includes BLUETOOTH service informationsupported by the wearable device, such as characteristic information ofthe BLUETOOTH protocol or a command of the BLUETOOTH protocol.Therefore, the network connection device may establish a mappingrelationship between the BLUETOOTH service information and the serviceinformation supported by the third communication connection, and storethe mapping relationship. When sending the first information to thewearable device, the network connection device may convert, according tothe mapping relationship, the first information sent through the thirdcommunication connection to the first information sent through the firstBLUETOOTH connection, and send the first information to the wearabledevice through the first BLUETOOTH connection.

When establishing the mapping relationship, the network connectiondevice mainly establishes a correspondence between each piece ofinformation in the BLUETOOTH service information and each piece ofinformation in the service supported by the third communicationconnection, for example, establishes a correspondence between a commandor a message in the BLUETOOTH protocol and a command or a message of theprotocol supported by the third communication connection.

(2) The user equipment indirectly configures that the network connectiondevice actively performs a BLUETOOTH pairing with the wearable device.

Step 105: The network connection device receives a procedure requestmessage sent by the user equipment, where the procedure request messageis used to request the network connection device to enable a BLUETOOTHpairing procedure with the wearable device, and the network connectiondevice enables the BLUETOOTH pairing procedure with the wearable deviceaccording to the procedure request message. That is, the networkconnection device actively sends a BLUETOOTH pairing request to thewearable device. When the pairing succeeds, the network connectiondevice may store information about the wearable device, includinginformation such as the BLUETOOTH address and the key. Further, thenetwork connection device generates the pairing relationship between theuser equipment and the wearable device.

(3) The user equipment indirectly configures that the network connectiondevice passively accepts the pairing with the wearable device.

Step 106: The network connection device receives a mode request messagesent by the user equipment, where the mode request message is used torequest the network connection device to enable a BLUETOOTH pairingmode, and the network connection device enables the BLUETOOTH pairingmode according to the mode request message to passively accept BLUETOOTHpairing with the wearable device. That is, the network connection deviceis set to a state of being searchable by another BLUETOOTH device withina period of time, and can accept a pairing request. When the pairingsucceeds, the network connection device may store the information aboutthe wearable device, including information such as the BLUETOOTH addressand the key. Further, the network connection device generates thepairing relationship between the user equipment and the wearable device.

A function of the pairing relationship between the user equipment andthe wearable device includes the user equipment first sends, to thenetwork connection device, the first information that is sent to thewearable device, and the network connection device sends the firstinformation to the corresponding wearable device according to thepairing relationship.

An embodiment of the present disclosure further provides anothercommunications method of a wearable device that may be applied to thecommunications system shown in FIG. 1A or FIG. 1B. The method of thisembodiment is a method performed by user equipment in the system. Aflowchart is shown in FIG. 4, including the following steps.

Step 201: The user equipment determines that a second BLUETOOTHconnection between the user equipment and the wearable device isdisconnected. Generally, a communication connection between the userequipment and the wearable device is a BLUETOOTH communicationconnection. When the user equipment detects no BLUETOOTH signal of thewearable device, or strength of a detected BLUETOOTH signal of thewearable device is less than a threshold, it is determined that thesecond BLUETOOTH connection between the user equipment and the wearabledevice is disconnected. In an embodiment, in another case, whendetermining a third communication connection to a network connectiondevice in a network to which the user equipment belongs is established,the user equipment may actively disconnect the second BLUETOOTHconnection to the wearable device. Therefore, when the thirdcommunication connection is established between the user equipment andthe network connection device, the second BLUETOOTH connection to thewearable device is disconnected.

It should be understood that, after the user equipment finds that thesecond BLUETOOTH connection to the wearable device is disconnected, if afirst BLUETOOTH connection between the network connection device and thewearable device is established, the user equipment may perform step 202.

The user equipment may actively trigger the network connection device toestablish the first BLUETOOTH connection to the wearable device. In anembodiment, the user equipment may send a triggering command to thenetwork connection device, where the triggering command is used toinstruct to establish the first BLUETOOTH connection between the networkconnection device and the wearable device such that the user equipmentmay indirectly communicate with the wearable device by using the networkconnection device. Therefore the user equipment considers that the firstBLUETOOTH connection between the network connection device and thewearable device is established, and performs a subsequent step 202. Inanother case, establishing the first BLUETOOTH connection between thenetwork connection device and the wearable device is triggered by thewearable device. After establishing the first BLUETOOTH connection tothe wearable device, the network connection device may send anannouncement message to the user equipment, where the announcementmessage is used to notify the user equipment that the first BLUETOOTHconnection between the network connection device and the wearable deviceis established such that the user equipment may perform the subsequentstep 202 according to the announcement message. When the user equipmentactively triggers the network connection device to establish the firstBLUETOOTH connection to the wearable device, after the user equipmentsends the triggering command, the user equipment further receive theannouncement message returned by the network connection device, and thenthe user equipment may perform the subsequent step 202.

Step 202: When the user equipment includes information that to be sentto the wearable device, the user equipment sends first information tothe network connection device through the third communication connectionto the network connection device to which the user equipment belongssuch that the network connection device may send the first informationto the wearable device through the first BLUETOOTH connection.

In an embodiment, the third communication connection between the networkconnection device and the user equipment may support a connection of theIP such that the user equipment may send the first information to thenetwork connection device by using the IP. In an embodiment, the firstinformation in a BLUETOOTH protocol format is carried in a payload of anIP packet and sent to the network connection device, or the userequipment sends the first information in an upper-layer protocol formatto the network connection device by using an IP packet, and upper-layerprotocols include but are not limited to the UPnP protocol, the DLNAprotocol, the IGRS, the HTTP, and the TCP.

The third communication connection may further be a connection thatsupports the UPnP protocol, and the user equipment sends the firstinformation to the network connection device by using the UPnP protocol.In an embodiment, the first information in the UPnP protocol format issent to the network connection device. The third communicationconnection may be a connection that supports the Wi-Fi protocol, and theuser equipment sends the first information to the network connectiondevice by using the Wi-Fi protocol. In an embodiment, the firstinformation in the BLUETOOTH protocol format is carried in a payload ofa MAC frame of the Wi-Fi protocol and sent to the network connectiondevice, or the first information in an upper-layer protocol format issent to the network connection device by using the Wi-Fi, andupper-layer protocols include but are not limited to the UPnP protocol,the DLNA protocol, the IGRS, the HTTP, the TCP, the UDP, and the IP.

The first information sent by the user equipment may be content, aninstruction, data, and the like that is sent by the user equipment tothe wearable device, and a format of the first information sent by theuser equipment to the network connection device may be the same as ordifferent from a format of the first information sent by the networkconnection device to the wearable device. When the user equipment sendsthe first information to the network connection device, a communicationsprotocol format supported by the third communication connection may beused, and when the network connection device sends the first informationto the wearable device, a BLUETOOTH protocol format is mainly used.Therefore, in a specific operation, the network connection device mayconvert first information in the communications protocol formatsupported by the third communication connection to first information inthe BLUETOOTH protocol format. For a method performed by the networkconnection device, refer to the foregoing descriptions in thisembodiment.

Further, the user equipment may receive, by using the network connectiondevice, second information sent by the wearable device. The networkconnection device receives the second information that is sent by thewearable device through the first BLUETOOTH connection, and the secondinformation may be a notification or data that is sent by the wearabledevice to the user equipment, information that is reported by thewearable device to the user equipment, or the like. The networkconnection device sends the second information to the user equipmentthrough the third communication connection to the user equipment. Aformat of the second information sent by the wearable device to thenetwork connection device may be the same as or different from a formatof the second information sent by the network connection device to theuser equipment.

Further, when any one of conditions occurs, the user equipment mayestablish the second BLUETOOTH connection to the wearable device, andthe user equipment sends the first information to the wearable devicethrough the second BLUETOOTH connection.

The user equipment finds a BLUETOOTH signal of the wearable device. Forexample, the user equipment finds that strength of a BLUETOOTH signal ofthe wearable device reaches a threshold.

After the third communication connection between the user equipment andthe network connection device is disconnected, the user equipment findsthe BLUETOOTH signal of the wearable device.

After the user equipment receives a second notification message sent bythe network connection device, where the second notification message isused to notify the user equipment that the first BLUETOOTH connectionbetween the network connection device and the wearable device isdisconnected, the user equipment finds the BLUETOOTH signal of thewearable device.

When the user equipment finds the BLUETOOTH signal of the wearabledevice, and when the user equipment does not perform informationinteraction with the wearable device by using the network connectiondevice in a preset time, the user equipment sends, to the networkconnection device, a request for disconnecting the first BLUETOOTHconnection.

It can be learned that in the method of this embodiment, if a secondBLUETOOTH connection between user equipment and a wearable device isdisconnected, a first BLUETOOTH connection may be established between anetwork connection device of the user equipment and the wearable device.When the user equipment finds that the second BLUETOOTH connection tothe wearable device is disconnected, the user equipment may send firstinformation to the wearable device by using the network connectiondevice. In this way, indirect communication between the user equipmentand the wearable device is implemented by using the network connectiondevice such that the user equipment and the wearable device cancommunicate with each other without being limited by a communicationrange.

It should be understood that the communications method in steps 201 and202 is the communications method that is used after devices in thecommunications system are configured, however, before step 201, the userequipment may separately configure the wearable device and the networkconnection device in following manners:

(1) The user equipment directly and separately configures, for thenetwork connection device and the wearable device, information requiredfor performing first BLUETOOTH communication between the networkconnection device and the wearable device.

The user equipment may send first configuration information to thenetwork connection device, where the first configuration informationincludes a BLUETOOTH address of the wearable device and a key forperforming BLUETOOTH communication between the network connection deviceand the wearable device, and may further include a pairing relationshipbetween the user equipment and the wearable device such that the networkconnection device stores the first configuration information. The userequipment may send third configuration information to the wearabledevice, where the third configuration information includes a BLUETOOTHaddress of the network connection device, and may further includeinformation such as a key for performing communication between thenetwork connection device and the wearable device.

Further, the user equipment may further send second configurationinformation to the network connection device, where the secondconfiguration information includes BLUETOOTH service informationsupported by the wearable device. Therefore, the network connectiondevice may establish, according to the second configuration information,a mapping relationship between the BLUETOOTH service information andservice information supported by the third communication connection, andstore the mapping relationship.

(2) The user equipment indirectly and separately configures a functionof the network connection device and a function of the wearable devicesuch that the network connection device may actively initiate aBLUETOOTH pairing procedure to the wearable device, and the wearabledevice may be passively paired with the network connection device.

The user equipment sends a mode request message to the wearable device,where the mode request message is used to request the wearable device toenable a BLUETOOTH pairing mode, that is, the wearable device is set toa state of being searchable by another BLUETOOTH device within a periodof time, and can accept a pairing request. The user equipment sends aprocedure request message to the network connection device, where theprocedure request message is used to request the network connectiondevice to enable a BLUETOOTH pairing procedure with the wearable device.

In an embodiment, the user equipment sends the procedure request messageonly to the network connection device, where the procedure requestmessage is used to request the network connection device to enable aBLUETOOTH pairing procedure with the wearable device, instead of sendingthe mode request message to the wearable device to enable the BLUETOOTHpairing mode. The wearable device is preset to enable a pairing mode,that is, is preset to a state of being searchable by another BLUETOOTHdevice, and can accept a pairing request. In a pairing process, thewearable device may prompt a user whether to accept pairing with thenetwork connection device. After the user determines to accept pairingwith the network connection device, the wearable device accepts thepairing with the network connection device.

(3) The user equipment indirectly and separately configures a functionof the network connection device and a function of the wearable devicesuch that the wearable device may actively initiate a BLUETOOTH pairingprocedure to the network connection device, and the network connectiondevice may be passively paired with the wearable device.

The user equipment sends the mode request message to the networkconnection device, where the mode request message is used to request thenetwork connection device to enable the BLUETOOTH pairing mode, that is,the network connection device is set to the state of being searchable byanother BLUETOOTH device within a period of time, and can accept thepairing request. The user equipment sends the procedure request messageto the wearable device, where the procedure request message is used torequest the wearable device to enable the BLUETOOTH pairing procedurewith the network connection device.

The following describes a communications method of a wearable deviceprovided in the present disclosure is described by using an applicationembodiment. In the communications system of this embodiment shown inFIG. 1A, user equipment communicates with a network connection device byusing the UPnP protocol, the network connection device communicates withthe wearable device by using the BLUETOOTH protocol, and the userequipment communicates with the wearable device by using the BLUETOOTHprotocol. In this embodiment:

1. The user equipment configures the network connection device and thewearable device. A flowchart is shown in FIG. 5A, including thefollowing.

(1) The user equipment obtains a BLUETOOTH address BD_ADDR1 of thenetwork connection device and a BLUETOOTH address BD_ADDR2 of thewearable device, and generates a key Link_Key for performing BLUETOOTHcommunication between the network connection device and the wearabledevice.

In an embodiment, the user equipment may obtain, by using a web clientinstalled on the user equipment, the BLUETOOTH address BD_ADDR1 of thenetwork connection device from a web server, that is, the networkconnection device, or the user equipment serves as a control point, andreads the BLUETOOTH address BD_ADDR1 from the network connection device(the network connection device is used as a UPnP device) by using theUPnP protocol.

(2) The user equipment sends information such as the BLUETOOTH addressBD_ADDR1 of the network connection device and the key Link_Key to thewearable device for storage.

(3) The user equipment sends information such as the BLUETOOTH addressBD_ADDR2 of the wearable device and the key Link_Key to the networkconnection device for storage. Optionally, the user equipment sendsinformation such as a pairing relationship between the user equipmentand the wearable device to the network connection device for storage.

If the network connection device receives no pairing relationshipbetween the user equipment and the wearable device, the pairingrelationship between the user equipment and the wearable device beestablished.

(4) The user equipment obtains BLUETOOTH service information supportedby the wearable device from the wearable device, and sends the BLUETOOTHservice information to the network connection device.

Therefore, the network connection device may establish a mappingrelationship between the BLUETOOTH service information supported by thewearable device and service information of the UPnP protocol, and mapthe wearable device to a UPnP root device of the network connectiondevice. For example, the network connection device establishes a mappingrelationship between configuration management service (CMS) informationof the UPnP protocol and heart rate service information supported by thewearable device

A. Map the BLUETOOTH address of the wearable device to a universallyunique identifier (UUID) of the UPnP root device.

B. Establish a mapping relationship between a function (action) and anevent in a CMS service and the GATT and a characteristic command in aBLUETOOTH protocol, for example

A value setting function (SetValues) in the CMS service corresponds to awrite request (Write Request) in the BLUETOOTH protocol, a valueobtaining function (GetValues) in the CMS service corresponds to a readrequest in the BLUETOOTH protocol, and a report event in the CMS servicecorresponds to a value handling notification in the BLUETOOTH protocol,and the like.

C. Establish a mapping relationship between a characteristic in theBLUETOOTH protocol and a parameter in a data model of a CMS service, forexample

Characteristics in the BLUETOOTH protocol, including a heart ratemeasurement, a heart rate measurement client characteristicconfiguration descriptor, a body sensor location, a heart rate controlpoint, and the like, are considered as parameters in the data model ofthe CMS service.

D. Establish a mapping relationship between a characteristic having anotify attribute in the BLUETOOTH protocol and status variable in theCMS service such that the wearable device may report a characteristicvalue, for example:

The heart rate measurement in the BLUETOOTH protocol is corresponding tothe status variable of the UPnP protocol.

2. The user equipment indirectly communicates with the wearable deviceby using the network connection device. A flowchart is shown in FIG. 5B,including the following.

(1) In a process of performing the BLUETOOTH communication between theuser equipment and the wearable device, if the wearable device does notreceive, within a period of time, a BLUETOOTH heartbeat packet sent bythe user equipment, it is determined that the BLUETOOTH connectionbetween the wearable device and the user equipment is disconnected. Inthis case, the wearable device continues to determine whether aBLUETOOTH paging message sent by the network connection device can bereceived. If the BLUETOOTH paging message sent by the network connectiondevice can be received, the wearable device may return a BLUETOOTHpaging response to establish a BLUETOOTH communication connectionbetween the network connection device and the wearable device.

In another specific embodiment (as shown by dashed lines in FIG. 5B), ifthe user equipment does not receive, within a period of time, aBLUETOOTH heartbeat response message sent by the wearable device, it isdetermined that the BLUETOOTH connection to the wearable device isdisconnected, and the user equipment sends the triggering command to thenetwork connection device by using the UPnP protocol to trigger thenetwork connection device to establish the BLUETOOTH communicationconnection to the wearable device.

(2) After the BLUETOOTH communication connection between the networkconnection device and the wearable device is established, anannouncement message is sent to the user equipment, where theannouncement message is used to notify the user equipment that the firstBLUETOOTH connection between the network connection device and thewearable device is established, or that the wearable device is in anonline state. For example, the announcement message is used to notifythe user equipment that a UPnP root device corresponding to the wearabledevice is in the online state, and the announcement message is SimpleService Discovery Protocol (SSDP) alive announcement message.

(3) After receiving the SSDP alive announcement message sent by thenetwork connection device, the user equipment may indirectly communicatewith the wearable device.

The user equipment sends the first information to the network connectiondevice by using the UPnP protocol, and the network connection deviceconverts the first information sent by using the UPnP protocol to thefirst information sent by using the BLUETOOTH protocol, and sends thefirst information to the wearable device. For example, the firstinformation sent by the user equipment to the wearable device isparameter value reading. The user equipment sends a GetValues ( )command of the UPnP protocol to the network connection device, and thenetwork connection device converts the GetValues ( ) command to the ReadRequest ( ) of the BLUETOOTH protocol and sends the Read Request ( ) tothe wearable device.

When the wearable device sends second information to the user equipment,the wearable device sends the second information to the networkconnection device by using the BLUETOOTH protocol, and the networkconnection device converts second information sent by using theBLUETOOTH protocol to second information sent by using the UPnPprotocol, and sends the second information to the user equipment. Forexample, the second information sent by the wearable device to the userequipment is heart rate reporting. The wearable device sends a heartrate measurement parameter value to the network connection device byusing a Handle Value Notification ( ) message of the BLUETOOTH protocol,and the network connection device converts the heart rate measurementparameter value to a notification event of the UPnP protocol and reportthe heart rate measurement parameter value to the user equipment.

(4) When the user equipment finds that strength of a BLUETOOTH signal ofthe wearable device reaches a threshold, the user equipment instructsthe network connection device to disconnect the BLUETOOTH connection tothe wearable device such that the user equipment may communicate withthe wearable device by establishing a direct communication connection.

The following describes a communications method of a wearable deviceprovided in the present disclosure by using another following specificembodiment. In the communications system of this embodiment shown inFIG. 1B, the method in this embodiment is similar to the method of theapplication embodiment corresponding to FIG. 1A. A difference is when anetwork connection device communicates with a wearable device by using abridge device, where the bridge device is connected to the networkconnection device by using an electrical power cable, and the bridgedevice mainly transmits a BLUETOOTH message sent by the networkconnection device or the wearable device.

An embodiment of the present disclosure further provides a networkconnection device, where the network connection device may be a gatewaydevice such as a Wi-Fi router. A schematic structural diagram of thenetwork connection device is shown in FIG. 6, including a communicationestablishment unit 11 configured to determine that a second BLUETOOTHconnection between user equipment and a wearable device is disconnected,and establish a first BLUETOOTH connection to the wearable device,where, the communication establishment unit 11 is configured to, after atriggering command sent by the user equipment is received, where thetriggering command is used to instruct to establish the first BLUETOOTHconnection between the network connection device and the wearabledevice, determine that the second BLUETOOTH connection between the userequipment and the wearable device is disconnected, and establish thefirst BLUETOOTH connection to the wearable device, or after a BLUETOOTHsignal of the wearable device is found, determine that the secondBLUETOOTH connection between the user equipment and the wearable deviceis disconnected, and establish the first BLUETOOTH connection to thewearable device, or after a BLUETOOTH signal of the wearable device isfound, send an acknowledgment request message to the user equipment,where the acknowledgment request message is used to request the userequipment to determine whether the first BLUETOOTH connection beestablished between the network connection device and the wearabledevice, and after an acknowledgment message returned by the userequipment is received, determine that the second BLUETOOTH connectionbetween the user equipment and the wearable device is disconnected, andestablish the first BLUETOOTH connection to the wearable device, aninformation receiving unit 12 configured to receive first informationthat is sent by the user equipment through a third communicationconnection to the network connection device, and a sending unit 13configured to send the first information received by the informationreceiving unit 12 to the wearable device through the first BLUETOOTHconnection established by the communication establishment unit 11.

It may be understood that, when establishing the first BLUETOOTHconnection between the network connection device and the wearabledevice, the communication establishment unit 11 may establish the firstBLUETOOTH connection to the wearable device by using a bridge devicethat communicates with the network connection device, and the sendingunit 13 is configured to transmit the first information to the bridgedevice, and the bridge device sends the first information to thewearable device through the BLUETOOTH connection to the wearable device.

It can be learned that in this embodiment of the present disclosure, ifa second BLUETOOTH connection between user equipment and a wearabledevice is disconnected, a first BLUETOOTH connection between a networkconnection device and the wearable device is established by using acommunication establishment unit 11, when an information receiving unit12 receives first information that is sent by the user equipment througha third communication connection to the network connection device, asending unit 13 sends the first information to the wearable devicethrough the first BLUETOOTH connection. In this way, indirectcommunication between the user equipment and the wearable device isimplemented by using the network connection device such that the userequipment and the wearable device are not limited by a communicationrange.
